Brassica napus. L Genome Annotation Database (BnaGADB) maintains a database of genome sequence along with gene sequence (DNA, RNA and protein sequences), gene structure, gene family, pathway, functional annotation, chromosome map, collinearity, duplicated gene pair, expression (e.g., development, hormone induction, and nutrient stress RNA-Seq datasets), alternative splicing information for the oild crop B. napus ecotype Zhongshuang11 (ZS11). BnaGADB also provides genome-wide information about other B. napus ecotypes and Brassicaceae species for comparative genomics analyses. These data are available through search pages. The datasets in BnaGADB is updated every year from the latest published research literature and our researches.
